Week 4, last assignment - what is needed from previous assignment

I’m realy sorry, but I do not understand how to begin…
It is said “Use the helper functions you have implemented in the previous assignment to build a 2-layer neural network with the following structure”.
But I do not understant if I have to

  • do nothing because the 2 notebooks are linked
  • copy/paste previous code in the new notebook
  • re-do all this code from scratch
    please advice

You don’t need to do anything special: the functions are automatically imported for you to use. You can just call them where you need to. No further action than that is required.
